Ka Moolelo o ka Nānā ʻana i ka Wai a me nā Pono Kāohi Chlorine ma Vietnam
Ma ke ʻano he ʻāina ʻoihana wikiwiki a me ke kūlanakauhale ʻana o ʻAsia Hikina Hema, ke kū nei ʻo Vietnam i nā kaomi pālua ma ka hoʻokele waiwai wai. Hōʻike nā helu helu ma kahi o 60% o ka wai honua a me 40% o ka wai o luna ma Vietnam ua haumia i nā ʻano like ʻole, me ka haumia microbial a me nā kemika nā mea nui e hopohopo nei. I loko o nā ʻōnaehana hoʻolako wai, ʻo ke koena chlorine - ma ke ʻano he ʻāpana chlorine hana i koe mai ka disinfection - he kuleana koʻikoʻi ia i ka hōʻoia ʻana i ka palekana o ka wai. ʻAʻole hiki i ka chlorine koena lawa ke hoʻopau mau i nā pathogens i loko o nā pipelines, ʻoiai hiki i nā pae kiʻekiʻe ke hana i nā huahana disinfection carcinogenic. Paipai ka WHO e mālama i nā koena chlorine ma waena o 0.2-0.5mg/L i ka wai inu, ʻoiai ʻo ke kūlana QCVN 01:2009/BYT o Vietnam e koi ana i ka liʻiliʻi he 0.3mg/L ma nā wahi hopena pipeline.
Hōʻike nā ʻōnaehana wai o Vietnam i nā ʻokoʻa koʻikoʻi ma waena o ke kūlanakauhale a me ke kuaʻāina. Loaʻa i nā wahi kūlanakauhale e like me Hanoi a me Ho Chi Minh City nā ʻōnaehana lako piha akā ke kū nei i nā pilikia mai nā paipu kahiko a me ka haumia lua. Ma kahi o 25% o ka heluna kanaka kuaʻāina ʻaʻole i loaʻa ka wai inu palekana, e hilinaʻi nui ana i ka luawai i mālama pono ʻole ʻia a i ʻole ka wai o luna. Hoʻokumu kēia hoʻomohala like ʻole i nā koi like ʻole no nā ʻenehana nānā chlorine - pono nā wahi kūlanakauhale i nā ʻōnaehana pūnaewele manawa maoli a kiʻekiʻe, ʻoiai ʻo nā wahi kuaʻāina e hoʻokau mua i ke kumukūʻai kūpono a me ka maʻalahi o ka hana.
Ua loaʻa i nā ʻano nānā kuʻuna nā pilikia he nui i ka hoʻokō ʻana ma Vietnam:
- Pono ka loiloi hale hana i 4-6 mau hola e nā limahana i aʻo ʻia
- Ua kaupalena ʻia ka laʻana lima e ka ʻāina lōʻihi o Vietnam a me nā ʻōnaehana muliwai paʻakikī
- ʻAʻole hiki i ka ʻikepili i hoʻokaʻawale ʻia ke hāʻawi i nā ʻike mau no nā hoʻoponopono kaʻina hana
Ua ʻike nui ʻia kēia mau palena i nā wā pilikia e like me ka hanana liki chlorine i ka makahiki 2023 ma kahi paka ʻoihana ma ka panalāʻau ʻo Dong Nai.
Hāʻawi ka ʻenehana sensor chlorine koena i nā hopena hou no ka nānā ʻana i ka wai o Vietnam. Hoʻohana nui nā sensor hou i nā loina electrochemical (polarography, constant voltage) a i ʻole nā loina optical (DPD colorimetry) e ana pololei i ka chlorine manuahi a me ka chlorine holoʻokoʻa, e hoʻouna ana i ka ʻikepili manawa maoli ma o nā pilina uea a uea ʻole paha. Ke hoʻohālikelike ʻia me nā ʻano kuʻuna, hāʻawi kēia ʻenehana i ka pane wikiwiki (<30 kekona), ʻoi aku ka pololei (± 0.02mg/L), a me ka mālama haʻahaʻa - kūpono loa no ke aniau wela o Vietnam a me nā pono nānā decentralized.
Hāʻawi nā hana "Smart City" a Vietnam a me ka papahana aupuni "Clean Water" i ke kākoʻo kulekele no ka hoʻohana ʻana i ka sensor chlorine. ʻO ka makahiki 2024Hōʻike Noiʻi Hoʻomohala ʻOihana a me ka Hoʻopukapuka Waiwai no ka mea loiloi Chlorine koena o Vietnamhōʻike i nā hoʻolālā aupuni e hoʻomaikaʻi i nā ʻōnaehana nānā ma nā kūlanakauhale nui, e hoʻokau mua ana i nā lako nānā chlorine pūnaewele. I ka manawa like, ua hoʻonui ke Kuhina Ola i ka pinepine o ka nānā ʻana i koi ʻia mai kēlā me kēia mahina a i kēlā me kēia lā ma nā wahi koʻikoʻi, e hoʻoikaika hou ana i ke koi no nā ʻenehana manawa maoli.
Papaʻaina: Nā Palena Chlorine Koena ma nā Kūlana Kūlana Wai o Vietnam
| ʻAno Wai | Kūlana Maʻamau | Palena Chlorine (mg/L) | Ka Nānā ʻana i ka Pinepine |
|---|---|---|---|
| Wai inu kūlanakauhale | QCVN 01:2009/BYT | ≥0.3 (kiko hope) | I kēlā me kēia lā (nā kiko koʻikoʻi) |
| Wai ʻōmole | QCVN 6-1:2010/BYT | ≤0.3 | No kēlā me kēia pūʻulu |
| Pūnāwai ʻauʻau | QCVN 02:2009/BYT | 1.0-3.0 | I kēlā me kēia 2 hola |
| Wai ʻino o ka haukapila | QCVN 28:2010/BTNMT | ≤1.0 | Hoʻomau |
| Hoʻomaʻalili ʻoihana | Nā Kūlana ʻOihana | 0.5-2.0 | Pili i ke kaʻina hana |
Hōʻike ka mākeke sensor Vietnamese i ka noho like ʻana o ka honua a me ke kūloko, me nā lama premium e like me LAR o Kelemania a me HACH o ʻAmelika e noho aliʻi ana i nā ʻāpana kiʻekiʻe ʻoiai nā mea hana Kina e like me Xi'an Yinrun (ERUN) a me Shenzhen AMT e loaʻa ana ka māhele mākeke ma o ke kumukūʻai hoʻokūkū. ʻIke ʻia, ke komo nei nā ʻoihana Vietnamese i ka hana sensor ma o nā hui ʻenehana, e like me nā sensor haʻahaʻa haʻahaʻa o kahi ʻoihana ma Hanoi i hoʻāʻo pono ʻia ma nā papahana wai kula ma nā wahi kuaʻāina.
Ke kū nei ka hānai kūloko i kekahi mau pilikia hoʻololi:
- Hoʻopilikia ka haʻahaʻa wela i nā mea uila
- ʻO ka turbidity kiʻekiʻe e hoʻopilikia ana i ka pololei o ka optical
- Ka lako mana manawa ʻole ma nā wahi kuaʻāina
Ua pane mai nā mea hana me ka pale IP68, ka hoʻomaʻemaʻe ʻakomi, a me nā koho mana o ka lā e hoʻoikaika i ka hilinaʻi i nā kūlana koi o Vietnam.
Nā Kumumanaʻo ʻenehana a me nā Hoʻololi Kūikawā ma Vietnam
Hoʻohana nā mea ʻike chlorine koena i ʻekolu mau ʻano hana ʻike mua ma Vietnam, kūpono kēlā me kēia no nā ʻano wahi a me nā noi like ʻole.
ʻO nā mea ʻike polagraphic, i hoʻohālikelike ʻia e ERUN-SZ1S-A-K6, e hoʻomalu i nā kikowaena kūlanakauhale a me nā ʻoihana. Ke ana nei kēia i ka ʻokoʻa o kēia manawa ma waena o nā electrodes hana a me nā electrodes kuhikuhi (ʻo ia hoʻi nā ʻōnaehana electrode gula), e hāʻawi ana i ka pololei kiʻekiʻe (± 1%FS) a me ka pane wikiwiki (<30s). Ma ka Hale Hana Wai No.3 o ke kūlanakauhale ʻo Ho Chi Minh, ua hōʻike nā hopena polagraphic i 98% kūlike me nā kūlana DPD hale hana. Hoʻonui nā ʻōnaehana hoʻomaʻemaʻe aunoa i hoʻohui ʻia (nā ʻōnaehana palaki) i nā manawa mālama i 2-3 mau mahina - he mea nui no nā wai waiwai i ka algae o Vietnam.
ʻOi aku ka maikaʻi o nā mea ʻike uila mau (e laʻa, nā ʻōnaehana LAR) i nā noi wai hoʻoneʻe paʻakikī. Ma ka hoʻopili ʻana i ka hiki paʻa a me ke ana ʻana i ke au hopena, hōʻike lākou i ke kūʻē ʻana i nā sulfides a me ka manganese - he mea waiwai nui ia ma nā wai kaumaha organik o Vietnam hema. Hoʻohana ka hale hana wai hoʻoneʻe ʻoihana ʻo Can Tho AKIZ i kēia ʻenehana me nā ʻōnaehana NitriTox e mālama i ka chlorine effluent ma 0.5-1.0mg/L.
Hoʻolako nā mea ʻike kala optical e like me Blueview's ZS4 i nā pono multi-parameter e noʻonoʻo ana i ka waihona kālā. ʻOiai lohi (2-5 mau minuke), ʻo ko lākou mana multi-parameter e pili ana i ka DPD (pH/turbidity like) e hōʻemi ana i nā kumukūʻai no nā pono hana panalāʻau. Ua hōʻemi nā holomua microfluidic i ka hoʻohana ʻana i ka reagent ma 90%, e hoʻomaʻamaʻa ana i nā kaumaha mālama.
Hiki iā mākou ke hāʻawi i nā ʻano hoʻonā like ʻole no
1. Mīkini lima no ka maikaʻi o ka wai me nā palena he nui
2. ʻŌnaehana Buoy lana no ka maikaʻi o ka wai me nā palena he nui
3. Palaki hoʻomaʻemaʻe ʻakomi no ka mea ʻike wai multi-parameter
4. Hoʻonohonoho piha o nā kikowaena a me ka module uea ʻole polokalamu, kākoʻo iā RS485 GPRS /4g/WIFI/LORA/LORAWAN
